QSFP-DD-400G-SR8 Module is 400GBASE-SR8 QSFP-DD PAM4 850nm 100m DOM Optical Transceiver Module

QSFP-DD-400G-SR8 Module Product Overview

QSFP-DD-400G-SR8 Module is designed to support 400G Ethernet, which is suitable for data center links up to 100m over multi-mode fiber with FEC. The module is compatible with IEEE 802.3cd 400GBASE-SR8 and IEEE 802.3cd 200GBASE-SR4. Moreover, QSFP-DD-400G-SR8 supports eight electrical interface lanes which operate in 50G PAM4 encoding mode resulting in 400G (8x50G) data rate. It is mainly used to connect multiple 400G signals from the server side (NICs) to the data center aggregation switch.
